We're dividing 866027 by 2 
Our goal is to divide 866027 by 2.

Let's proceed to step 1:
8 divided by 2 is 4 with a remainder of 0.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 8 from 8 to get 0.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 2

Moving on to step 2:
2 goes into 6 3 times with a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 43.0
The remainder is 0 after subtracting 6 from 6.
Fetch the next digit (6) from the dividend, attach it to 0 and continue: 6 / 2

Moving on to step 3:
2 can be fit into 6 3 times, resulting in a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 433.0
Subtracting 6 from 6 leaves us with 0.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 2

On to step 4:
When dividing 0 by 2, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 4330.0
Subtract 0 from 0 to get 0.
Grab the next digit (2) from the dividend, add it to 0, then carry on: 2 / 2

Step 5:
2 can be fit into 2 1 times, resulting in a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 43301.0
Subtract 2 from 2 to get 0.
Take the next digit (7) from the dividend and append it to 0, then repeat: 7 / 2

On to step 6:
2 can be fit into 7 3 times, resulting in a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 433013.0
The remainder is 1 after subtracting 6 from 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 7:
10 divided by 2 is 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 433013.5
If we take 10 away from 10, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 8:
2 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 433013.5
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 9:
The number 2 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 433013.5
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 433013.5, with a leftover of 0.0.
